 The Indiana Department of Correction concluded that its recent transfer of 600 inmates over six weeks from Arizona to a new section at New Castle increased tensions at the facility, as the inmates comprised a large group and prison staff lacked experience.The department held the inmates responsible for the riot.Following the riot, Indiana authorities suspended further transfers of Arizona inmates, pending measures to help out-of-state inmates adjust to Indiana prison policies, and to ensure that inmates were transferred more gradually to be able to integrate them into the prison population at New Castle.
